Here is a good link to learn about composites.
There are many good books on composites and design of model aircraft as well.
I have been playing around with the idea of building an x-3 out of composites at 12% size.Its only on scratch paper for now.
I may never get it done but it leads me to learn new things.When we leave our comfort zone and our existing skill set, we begin to learn. Who knows, You may be the next Kelly Johnson.
Good luck and best wishes on your project.
